SECJ0384E: Trust Association Init Error - Websphere

This is a discussion on SECJ0384E: Trust Association Init Error - Websphere ; Hello all,
I'm running Websphere 6.0.2.27 on a redhat linux server.
I had a situation where I had to reset the passwords for both wasdamin adn isadmin userids using the following commands.
DirectoryAdmin.sh -user -userid isadmin -password [password]
AppServerAdmin.sh -was ...

After these passwords reset, the WAS and DataStage processes started successfully and I was able to login both WAS console and Infomation Server and navigate web pages without any problem so far.
But when scanning the SystemOut.log in the WebSphere directory, I've noticed "AWXRB0008E error with SECJ0384E: Trust Association Init Error" mesage.
